> After [1] was implemented, there are some improvements seems still required:
> #  If no explicit tx is specified it`s possible to obtain situation when keys from one bulk enlisted under different tx [2]
> # Implicit tx (not tx at all but tx meta - timestamp, first enlisted partition and so on ..) need to be replicated into all calcite execution fragments.
> Thus in [3] seems we need to start implicit tx if no explicit defined and correctly process it in [4]
